Course Projects

Sep. 2018 -- Jun. 2022

These course projects were completed in my undergraduate courses, covering various programming languages. I worked as a designer and programmer in all of them and accomplished most work.

Intelligent Cloud Gallery

Jun. 2020 -- May 2021

This project created a digital photo album that demonstrated photos, artworks, and dynamic images to users based on current environmental conditions, date, and user preferences and matched music to pictures, providing users with a diverse artistic perspective. The voice assistant answered questions about artworks and enabled users to control the photo album in voice.

High-Resolution Road Disaster Monitoring and Assessment System

Aug. 2020 -- Jun. 2021

This project was proposed by National Disaster Reduction Center of the Ministry of Emergency Management of People’s Republic of China and completed by Pattern Recognition and Intelligent Vision Laboratory of Beijing University of Posts and Telecommunications. It aimed to construct an artificial intelligent assisted system to monitor geological disasters and assess road damage through remote sensing images taken by satellites.

Deep Learning Based Human State Assessment System

Oct. 2021 -- June 2025

This project construct a non-contact human state assessment system to monitor the realtime state of drivers and alert when abnormal state is predicted through videos captured by only one or two cameras. This system including target detection, keypoint detection, head pose estimation and time series prediction algorithms.

Large-Scale Distributed Mobile Ad-hoc Network Emulation System

Mar. 2022 -- June 2025

This project constructed a communication emulation system deployed in a distributed framework and managed by Kubernetes. The system utilized Docker to create containers as independent nodes and emulated the effect of physical layer and data link layer through its highly flexible model plugin.

Damaged Road Extraction Based on Simulated Post-Disaster Remote Sensing Images

Published in 2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021

Damaged road extraction is a challenging task in the field of remote sensing. Some existing methods include the step to extract road from pre- and post-disaster remote sensing images of the same area. In practice, it often occurs that one of these two images is missing. To solve this problem, we use CoCosNet, the model for exemplar-based image translation, to translate pre-disaster images to simulated post-disaster ones. Then we use D-LinkNet, the state-of-the-art method in road extraction, to extract road from the pre- and post-disaster images of the same area. We extract damaged road area by comparing pre-disaster road masks with post-disaster ones and output the damage level by calculating the proportion of the damaged road area. Finally, we evaluate the damaged road extraction accuracy. Experimental results on simulated post-disaster images prove the effectiveness of the simulation method and the framework for damaged road extraction and damage level evaluation.

Asynchronous Federated Learning via Over-the-Air Computation in LEO Satellite Networks

Published in IEEE Transactions on Wireless Communications, 2024

Owing to its ability to offer collaborative data utilization while ensuring data privacy, federated learning (FL) provides a promising paradigm to enable cooperative intelligent tasks across multiple low-earth orbit (LEO) satellites, such as carbon estimation, traffic surveillance, and forest fire detection. Although the advantages of pushing intelligence to satellites are multifold, limited communication channels along with the rigid global model aggregation conditions result in dramatic convergence delays. In order to reduce the convergence time, we propose an asynchronous FL framework in LEO satellite networks by exploiting multiple high-altitude platforms for model aggregation, where the advanced over-the-air computation (AirComp) transmission scheme is utilized for the sake of further reducing energy consumption. Considering the practical constraint of AirComp signal distortion, the objective function of optimizing FL performance is carefully formulated and solved by the proposed quantity-quality jointed linkage search algorithm. Simulation results demonstrate that our proposed asynchronous FL framework outperforms the conventional synchronous FL framework by a decline of 30.07% in convergence time at most. It also provides an average increase of 110% and 580%, respectively, in terms of throughput and energy efficiency in all scenarios considered. Overall, our study presents a beneficial asynchronous FL framework and a fast aggregation scheduling algorithm in LEO satellite networks, accelerating the convergence of the global model with reduced energy expenditure.
